INKING ATTACHMENT FOR PRINTING-PRESSES.

Specification of Letters Patent.

Patented Jan. 11-, 1916.

Application filed August as, 1914. Serial No. 859,018.

To all whom it may concern Be it known thatI, JOHN C. POFFENBAR- GER, a citizen of the United States, and a resident of Peoria, in the .county of Peoria and State of Illinois, have invented new and useful Improvements in Inking Attachments for Printing-Presses, of which the following is a specification.

My invention relates to improvements in printing presses and particularly to inking attachments therefor, the principal object being to provide a construction wherein in the ordinary platen printing presses, a uniform distribution of inkmay be readily obtained.

A further object of the invention is the provision in a press of the type mentioned,

' of an ink distributing cylinder and suitable mechanism for operating the parts to secure eflicient distribution of the ink.

Another object of this invention is the provision in printing presses, of an ink distributing cylinder, means for driving the same and form inking rollers and means for moving said form mkmg rollers over the form and in contact with said cylinder and for holding said rollers in contact with the cylinder for several revolutions.

A further object of the invention is the provision of such a construction which may be readily arranged or attached to existing standard forms of platen presses Without the necessity of reconstructing or rearranging them.

To the accomplishment of the foregoing and such other objects as may hereinafter appear, my invention consists in the combi nation, construction and arrangement of parts hereinafter described, and then sought to be defined in the appended claims, reference being had to the accompanying drawings forming a part hereof, and which shows merely for the purpose of. illustrative disclosure, a preferred embodiment of my inyention, it being understood that various "changes may be made in practice \v1thin the scope of the claims, without digressing from my inventlve idea.

In the drawings, Flgure 1 represents a rear elevation of an ordinary form of platen press with my invention applied thereto,

parts being broken away to facilitate disclosure; Fig. 2 1s a view of the press having my inventlon applied thereto, the press be- 53 -ing shown in open position and parts being broken away'to facilitate disclosure; Fig. 3

is a View similar to Fig; 2, theparts being shown closed; Fig. 4 1s a detailed view of a roller wing carrying the rollers and connections for operating the same, the parts being shown in a position assumed when the press is closed; Fig. 5 is a view similar to Fig. 4c, the parts being shown in a position assumed when the press is open; Fig. 6 is a detailed view of the means for shifting or vibrating the ink distributing cylinder.

As at present constructed with the disk form of ink distribution, the ordinary platen job presses are faulty, due to the inefficient distribution of ink and it is the principal object of my invention to improve this dis tribution. I do this, by mounting'an ink distributing cylinder in place of the disk, so that an effective transfer of the ink from the fountain to the inking roller occurs. In supplying this idea to existing forms'of presses, it is only necessary to remove cer tam parts and add others, the construction being readily adaptable for substitution inbed frame 3 also mounted thereon to swing.

to and fro as is well understood, the bed being indicated as 4:.

5 designates the main driving shaft, hav ingthe bevel gear 6 thereon meshing with bevel gear 7 on the end of the downwardly extending shaft 8, which shaft has the bevel gear 9 meshing with bevel gear 10 which is loose on the lower shaft 11, this being the shaft on which the bed carrying frame is pivoted. Bevel gear 12 on the upwardly ektending shaft 13 meshes with the other side of bevel gear 10 and has the bevel gear 14 on its upper end, which meshes with the bevel gear 15 on shaft 16 having the gear or pinion 17 on its other end. It is to be understood that these shafts are suitably journaled in the frame parts. This gear or pinion meshes with'the idler gear or pinion 18 which in turn meshes with gear or pinion 20 secured to shaft 21 to which the ink distributing cylinder 22-is connected. This cylinder is shifted by means. of the tongue or hub portion thereof, as is well understood in this art. It is therefore to be seen that I have provided a connection from the main driving shaft to the ink distributing cylinder whereby the same is driven at all times during the operation of the press, it being evident that. the form or type rollers are 013' erated in substantially the same manner as heretofore and without the necessity of any reconstruction so as to take the ink from the cylinder and ink the form. These form or type rollers 25 are connected to the shanks or shafts 26 which are slidably mounted in the sockets 27 in the roller, wings or carriers 28, being held properly by means of springs, not shown. This construction is well known in this art and a detailed description thereof is not necessary, it being understood that the bed is reciprocated by means of the link 29 and crank disk 30, the wings or carriers being pivotally mounted on the shaft 29 and caused to be rotated by means of the link 31 and its connections, due to the reciprocation of the bed. I provide means for limiting the swinging movement of these wings or carriers and consequently the rollers in the form of the link 31 which is normally held downwardly by spring 32 and has the elongated slot 33 in its outer end, which slot has the recess or socket 34 at its extreme end. The pin or member 35 on the wing engages said slot so that the movement of the wing is limited. In its open position, the wing is held securely by means of the pin engaging said socket 34, as shown at Fig. 5, but when the wing is started in its upward movement, the engaging lug or member 36 lifts the link so that the pin is moved from engagement with said socket 34 and the wing travels a suitable distance so that the rollers are brought in contact with the ink distributing cylinder, as shown in Figs. 3 and 4. This is necessary, for the reason that in a construction of this character, the rollers do not have to travel so far as in the type of press where the disk form of distribution is used. Another purpose for the provision of this slot 33 is that when the roller carriage and rollers reach the upper limit of their movement and the rollers are in contact with the ink distributing cylinder, the link 31 will slide on the pin or member 35 so as to produce a dwell in the movement of the carriage and rollers and thereby hold or lock the rollers in contact with the ink distributing cylinder for several revolutions thereof, whereby an effective supply and distribution of ink are obtained. The roller carriage and rollers remain in this position, until on the return movement of the link 31, the pin or member 35 rests in the recess or socket 31. Then the downward movement of the carriage and form or type rolls will be initiated. The provision of this means for causing the form or type rollers to dwell or remain in the stationary position in contact with the ink distributing roller, during several revolutions of the form or type rolls is very important in the effective and proper distribution of the ink.

Certain other details of the press are shown, but it is not believed to be necessary to describe them as they are not within the purview of this invention, it being limited to the ink distribution and the operation thereof.

It is therefore seen that I have provided a construction which can be readily attached to standard forms of platen presses, whereby a uniform distribution of ink is obtained, which operates simply and efficiently to produce the desired results and which may be installed cheaply and easily.

it is to be noted that for the purpose of illustration, I have used the type of press known to the trade as the Gordon press, as it is a standard type of machine and one which adapts itself readily for the attachment of my invention. It is to be understood that 1 use the ordinary form of fountain for supplying the ink to the cylinder and also use the usual riders in connection with the ink distributing rolls.

As stated hereinbefore, a large number of these details are omitted for the reason that they do not add anything to the disclosure and are not embodied as part of my inven tion.
